Prime Minister Recep Tayyip Erdogan served as a pallbearer at a funeral Monday for some of the 17 people killed by bombs in Turkey's biggest city, an attack the government blamed on Kurdish rebels who have targeted civilians in the past.

Turkish officials suggested Monday that Kurdish militants were the main suspects in bomb blasts that killed 17 people in a crowded square, with Turkey's prime minister saying it could be a reprisal for air raids on guerrilla positions in northern Iraq.
